Ecology Tue, 16 Feb 2016 07:40:02 ESTnews374829812Astronomers explain the low number of discovered grazing planets(Phys.org)—Exoplanet hunters have so far found hundreds of alien worlds using the transit method. They observe the visual brightness of the star, which drops when a planet crosses in front of the parent star's disk. However, only a handful of grazing exoplanets—meaning exoplanets that partially transit the host-star's disc—have been detected and confirmed. Astronomers from the University of Porto in Portugal blame giant dark polar spots on host stars for the difficulties of finding new grazing planets. Their research appears in the November issue of Astronomy & Astrophysics journal.http://phys.org/news/2015-11-astronomers-grazing-planets.html

These are the findings of Jonathan Batchelor and William Ripple of Oregon State University in the US, lead authors of a study published in Springer's journal Environmental Management.

The aim of the initiative is to identify, demonstrate and transfer best practices in pasture management and propose that stockbreeders and farmers adopt regenerative agriculture techniques that will allow the soil to be managed more effectively and more sustainably. For this project, Neiker-Tecnalia's partners are the Navarrese Institute of Food Technologies and Infrastructures (INTIA) and the Municipal Public Corporation of Orduña Town Council (Urdeñuderra S.L.).
